I've updated the converter to 0.40 version.
This version aims at usage improvements and fixes some bugs in process control.
Mencoder has been updated to 1.0rc7 version.

Have a go, it's a really nice update!

Reggie, it should support some .mov files, but not all. It seems that mencoder is not capable of converting the most recent mov. I tried with the new king kong trailer, and that's not working.
